I just got this 1967 La San Marco 69 (nice) up and running this week, and this video is the second shot pulled. I am pretty impressed even now at how forgiving the machine was in terms of testing. Hardly any persistent leaks were found so far.
The rattling noise when I pull the lever down is a stainless ball in the group one way valve rattling around inside its cubby hole and is to be expected. It prevents water going back into the boiler during extraction.
Pulled with 15g of Saka Caffè Espresso Bar
